Using Cloud Zoom with Products

Create a product and add a featured image

Save the product and preview it - Cloud Zoom should now be working on your product

Product variation images will also be zoomed with Cloud Zoom inside the featured image area.

Additional product images will be displayed in the usual thumbnail format, but clicking on a thumbnail will now make a new zoomable image to be loaded inside the featured image area.
The featured image will also automatically be added as an additional thumbnail if additional images are present.
